VAPPARATUS FOR COMPACTING CONCRETE OR THE LIKE.

Application filed November 26, 1921.

To all whom t may concern:

Be it known that I, FRANK N ossEK, :a citizen of the United States, anda resident of the city of Chicago, county of Cook, and

5 State of Illinois, have invented certain new and useful Improvementsin Apparatus for Compacting Concrete or the like, of which the followingis a specification.

' This invention relates to apparatus for l compacting concrete or thelike, and has for its object the provision of apparatus of thischaracter which will alternately raise a receptacle containing wetconcrete, and drop same against an unyielding body, so that the concreteis packed into a compact mass, thereby obviating the necessity fortamping or pressing, ordinarily necessary in the preparation ofconcrete, particularly concrete building blocks.

Another object of the invention is to provide means for forming theconcrete into blocks or other shapes during the compacting operation.

Other and further objects will appear 25 hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention vwill be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is a top plan view of the invention,

Fig. 2 is a side elevation of the invention,

Fig. 3 is an end view of the invention,

Fig. 4;is a perspective detail view of one of the molding membersemployed in the invention,

Fig. 5 is a sectional view on line 5-5 of Fig. 2,

Fig. 6 is a sectional View on line 6-6 of F ig. 5, and

Fig. 7 is a modified form of operating means for said apparatus,

-The invention consists of a frame of any suitable construction. Suchframe is preferably formed of parallel longitudinal timbers 1 and 2,which form the base of the frame. Preferably disposed on the upper sidesof saidl timbers 1 and 2, are transverse timbers 3 and il, the timbers 4having their Serial No. 517,879.

opposite ends fastened to the timbers 1 and 2 by suitable bolts. Theends of the timbers 3 may be fastened to the ends of the timbers 1 and 2by any suitable means, but I preferably employ boltsV 5, each of whichis threaded at one end to receive a nut thereon, and provided with acollar 6 a suitable distance from the opposite end for binding themembers together, the extremities of the bolts 5 forming upstandingstuds 7. Mounted to normally rest on the timbers 3 and 4c is a platform8, which isI provided adjacent its corners with apertures havingdisposed thereabout guide plates 8, such apertures and guide platesbeing adapted to loosely and movably engage the studs 7.

Preferably mounted on the platform 8, are longitudinally extendingchannel bars 9, suoli bars being held in position on said platform byany suitable means, clamps 10 being shown. Channel bars 11 arepreferably disposed between the ends of the bars 9, and held in positiontherebetween in a manner hereinafter set forth, the channel bars 9 and11 together forming a rectangular bed.

Within the bed formed by the channel bars 9 and 11, I preferably mount aplurality of angle bars 12, as shown in Fig. 4, such angle bars beinglongitudinally disposed end to end, to form parallel rows, as

shown in Fig. 1. For properly spacing and retaining said bars inposition in said bed, I preferably provide members 13, having slots 14in their opposite faces, adapted to receive therein the ends 15 ofadjacent angle bars 12, as shown in Fig. 1, the lower edges of th-emembers 13 being adapted to rest on the edges 16 of the bars 12 as shownin Fig. 6.

For binding the bed and partition members in position, and for retainingthe end bars 11 in position, I provide U bolts 17, preferably one foreach end of the bed, such bolts extending through the ends of thechannel bars 9 on the outside of t-he bars 11, and being threaded toreceive nuts on their ends. Preferably mounted in the bend of each ofthe U bolts 17, is a lever 18, having a cam head 19 adapted in operativeposition to abut against the side of the channel bar 9, to force sameinwardly so as to securely bind the members together. 7hen the leversVare thrown to inoperative position, the adjacent channel bar 9 is freeto move enough to permit removal of the members 11, 12, and 13.

Preferably mounted on the timbers 1 and 2 are suitable bearings 20 inwhich are journalled opposite ends of shafts 21 and 22. Mounted on shaft21 adjacent the end there-V of, is a sprocket wheel 23, and mounted onthe end of the shaft 22, is a sprocket wheel 24, there being a chain 25connecting said sprocket wheels as best shown in Figs. 1 and 2. Asuitable driving pulley 26 is mounted on the shaft 22 for driving thesprocket wheels and chain when power is traiismited to said pulleythrough a suitable belt 27 connected to a source of power l(not shown).Keyed on the shafts 21, 22, are cams 2S and 29` which are adapted tooperatively engage suitable rollers 30 mounted in the brackets 31secured to the under surface of the platform 8. By this arrangement, itwill be observed thatwhen power is transmitted to the sprocket .wheels23, 2&1, the cams will rotate and raise the platform 8 through a contactwith the rollers 30, the shape of such cams being such las. to cause asudden dropping Iof the platform when it has reached thel limit of itsupward movement, permitting` same to forcibly strike against the,timbers 3 and 1l of the frame.

In Fig. 7,1 have shown a modification of means for vibrating thel bed,in this construction there being an arm 31 keyed on a shaft 32, saidyshaft having mounted thereon, a hand lever 33.. A bearing plate 34 ismounted on the platform 35 and is engaged by a suitable roller mountedon the arm 3l. By this arrangement, oscillation of the lever will raiseand lower the plaforin in the desiredl manner. A Y

In operation, the apparatus is arranged as above described, and filledwith Vwet concrete. Power is, then transmitted to the cams which raiseand drop the platform onto the members 3 and 4, thus shaking down andcompacting the concrete thereon. It is usually desirable to shake theplat- -forin approximately one-half hour, in order to thoroughlyVcompact the concrete thereon, the concrete then being permitted to setfor approximtely twelve hours. Then it may be removed from theapparatus, and in approximately twentyfour hours, is ready for handling.By use of my apparatus, a superior product is produced at a great savingof time.

While l have illustrated and described the `preferred form ofconstruction for carrying my invention into eect, this is capable ofvariation and modification without departing from the spirit of theinvention. l,

therefore, do not wish to be limited to the precise details ofconstruction set forth, but desire to avail myself of such variationsand modifications as come within the scope of Y the appended claims.
